Is there any practical reason to prefer bind mounts or separately
mounting a subvolume?
e.g. assuming /locationA and /locationB are arbitrarily far apart in the
file system tree, is there any reason to prefer one of the following
over the other
mount -t btrfs -o subvolume=/thing /dev/sdN1 /locationA
mount --bind /locationA /locationB
vs.
mount -t btrfs -o subvolume=/thing /dev/sdN1 /locationA
mount -t btrfs -o subvolume=/thing /dev/sdN1 /locationB
Are both equally efficient and whatnot?

Internally, they're actually identical.
